Control Circuit for Electronic Devices, Electronic Circuit, Electro-Optical Apparatus, Driving Method for Electro-Optical Apparatus, Electronic System, and Control Method for Electronic Devices

1. A control circuit which serves as a drive circuit for electronic devices, the control circuit comprising: a device to generate a control signal based on a digital signal so as to control the electronic devices by the generated control signal, the control signal being set in each first period, and the control signal being set in each second period, which is different from the first period; a first current-value setting device setting a current value of the control signal in each of the first period based on part of digital data forming the digital signal; and a second current-value setting device setting the current value of the control signal in each of the second period based on the remaining data other than the part of the digital data used by the first current-value setting device for a portion set by said first current-value setting device based on the same digital data of the control signal.

2. A control circuit which serves as a drive circuit for electronic devices, and which generates a control signal based on a digital signal so as to control the electronic devices by the generated control signal, the control circuit comprising: a first current-value setting device to set a current value of the control signal in each first period; and a second current-value setting device to set the current value of the control signal in each second period, which is different from the first period, the second period being shorter than the first period, wherein the first current-value setting device setting the current value of the control signal in each of the first period based on part of digital data forming the digital signal, and the second current-value setting device setting the current value of the control signal in each of the second period based on the remaining data other than the part of the digital data used by the first current-value setting device for a portion set by said first current-value setting device based on the same digital data of the control signal.

3. The control circuit according to claim 2 , upper bits of the digital data being assigned to the part of the data, and lower bits of the digital data being assigned to the remaining data.

4. A control method for generating a control signal based on a digital signal so as to control electronic devices by the generated control signal, the control method comprising: first setting a current value of the control signal in each first period; and second setting the current value of the control signal in each second period, which is different from the first period, the second period being shorter than the first period, wherein the first setting including setting the current value of the control signal in each of the first period based on part of digital data forming the digital signal, and the second setting including controlling the current value of the control signal in each of the second period based on the remaining data other than the part of the digital data used by the first setting for a portion set by the first setting based on the same digital data of the control signal.

5. The control method for electronic devices according to claim 4 , further including assigning upper bits of the digital data to the part of the data, and assigning lower bits of the digital data to the remaining data.
